' kJONES, OF NIANTIG, ILLINOIS WATER HEATER OR BOILER Application filed June 5. 1926. Serial yNo.y 113,874.

i rlhis invention relates to improvements in water heaters or boilers and the principal object t iereof is the provision of a structure which will efficiently and eli'ectively heat water to a high degree ot temperature without the necessity of the use ot a plurality et tubes, sections and the like. The apparat-us may be designed for coal, gas or oil burning and for hot water, steam and pressure tank heating for home or domestic use as well as for business andpublic building use, and also may be usedyfor generating steam for power pur noses.

Another object of the invention is the provision of such a construction which is simple and readily made and assembled and may be formed in sections so as to facilitate installations of the larger constructions and also including the other advantages hereinafter set forth at length. n j

To the accomplishment of the foregoing and `suoli other objects as may hereinafter appear', this invention consists in the construction, combinatien and arrangement of parts hereinafter described and then sought to Lbe defined in the appended claims, refer ence being had to the accompanying drawings part li. olf and which show,

closure a preferred embodiment of my invention, being expressly understood, however, that various changes may be made in ,in the scope et the claims with-l out digressnig .trom my invention idea.

l ln the drawings- Figure 1 is a vertical sectional view of heater constructedto embody my invention, parts being shown in elevation to facilitate y he disclosure.

`Figure 2 is a horizontal cross section on f lino B-B oit Figure 1 showingT the front halt o1 the construction only.

yFigure 3 is ra top plan view of the secondary eomlmstion chamber and associated parts with the dome plate 17 removed.

Figure 4 is a vertical transverse cross section tarzcn substantially on line Df-D or Figures 1 and 3. f

Referring now to the drawings the numeral 1 designates a casing which may be ot any .size or shape and may be sectional or made 1n as tew pieces or parts as possible. It is provided with the customary appurtenances tor tiring operation including the grate, fire pot, ash pit and the like, these parts not being shown because they form no part of my invention. However, 2 designates the ash pit door and 3 the lire door.

Mounted within this casing 1 are the water heating casings or elements whichinclude the combustion chamber 4, a secondary combustion chamber 5 connected with the first-mentioned combustion chamber 4 by means of upwardly extending flue 6, an outlet pipe or Conduit 7 communicating with the secondary combustion chamber 5 by means of flue 8; the outlet Hue 7 also communicates with the upwardly extending lflue 6 as at 9 and has the damper 10 provided adjacent the junction therewith. The position of the damper is regulated by the adjusting means 11. The combustion chamber 4 has its top or crown sheet 12 bent or formed with a downwardly curved portion 13 where the upwardly ex-y tending flue 6 lits the opening into the combustion chamber 4, kfor the purpose of directthe hot gases and products of combustion downwardly, as indicated by the arrows, be- 'lfere egress through the upwardly extending `flue (i. The joints of all of these parts are w ght so that the outer casing is filled with water, which has contact with all of heated casings or elements, as shown particularly in Figure 1 ot the drawing.

The secondary combustion chamber 5 is a very important feature ot this invention. It includes a iiat bottom plate or member 14 having the opening 15 at one end to communicate with the upwardly extending i'lue 6 and the opening 16 at the other end to communicate with the line 8. This plate 14 is of substantially ovoid shape (see Figure 3) and the opening 15 is much larger in cross sectional area than the opening 16. These openings correspond in size to the cross sectional areas of the flues 6 and 8, the flue 6 being much greater in cross .sectional area than the tlue 8. The dome plate or member 17 is shaped to fit the bottom plate 14 and is semi-circular in vertical transverse section discharge is less than the rate ot inlet. The [pipe or conduit 18 may be of various shapes or" an air inlet pipe or conduit 18 which has its inlet end 19 extending without the casino' 1, the pipe or conduit 8 extending for the major portion ot' its length along the side ot 'he 'Hue G until it enters the secondary cornbustion chamber 5 where it is bent or curved as at 2O (see Figures 1 and 3, respectively). rllhe inlet end 19 may be controlled by any suita le damper (not shown) and it is tncretore seen that being drawn into or conduit 18 passes upwardly the-ren r and is discharged therefrom in a wgn or turning motion so that it mixes with hotgases and products of combustion, which are comparatively slowly passing through the secondary combustion chamber 5 due to the tact that the inlet flue is ot greater size than the outlet flue, and1 therefore` the rate ot but'l have found that it it is datt ned or ot considerable width, as shown in Fgure 3 ot the drawing, better results are obtained.

This construction results in very rapid heating ot the water as all of the heating surfaces of the casings or elements are in contact with the water which substantially surrounds all ot the surfaces, thereby giving the possible area ot cont-act between the water and the heating surfaces. he construction of the combustion chamber croi sheet or top plate causes the gases and pre ucts of combustion to be directed baclv down over the lire and thus causes what mi ht be termed a second combustion ot the individual particles which otherwise would pass directly into the flue 6. The hot gases and products of combustion then pass through ilue 6 into the secondary combustion chamber 5 through kwhich they pass relatively slowly and subjected to theV whirling action of the 'fresh air or oxygen and mixing therewith produces a secondary combustion. These hot gases and products of combustion then pass downwardly through the-flue 8 into the outlet tine 7. This outlet lue 7 has a direct connection with the upwardly extendingr line 6 which is open when tiring or shaking down the ashes,as is well understood.
